NPort Express DE-211 Introduction

7

NPort Express DE-211 provides a data communications solution for
connecting Windows and Linux hosts to asynchronous serial devices over
a TCP/IP Ethernet. You may connect your Windows host to a native
RS-232/422/485 serial port, or your PC-based Linux host to a real tty port,
through a TCP/IP Ethernet. With one asynchronous serial port connection
on one end, and a 10 Mbps Ethernet connection on the other, NPort
Express allows virtually any serial device to attach to a network. NPort
Express works like an add-on single-port serial board to your PC server,
but with one major advantage—the TCP/IP network. Since the host
communicates with the COM port on NPort Express over a TCP/IP network,
you are able to control your asynchronous serial device from virtually any
location.

Although it connects through the virtual link of the Ethernet, the port on
NPort Express is recognized as a real COM port by Windows or a real tty
port by Linux. NPort Express provides both the basic transmit/receive
data functions, as well as RTS, CTS, DTR, DSR, and DCD control signals.

NPort Express can be used with your existing applications that support
serial communication, and come with a utility program providing a simple
step-by-step installation procedure and a maintenance wizard that gives
you easy access to your asynchronous device.

Switch SW1 controls the function of the serial port (ON, or up, for RS-232
Console connection, and down for Data Communication, such as when
NPort Express is connected to your serial device). Note that after
changing the setting of SW1, NPort Express will reboot to in itialize the
new setting. You must wait a few seconds for the green Ready light to
blink off and then on again, indicating that the function of the serial port
has been changed.

Switches SW2, SW3, and SW4 control the serial port’s data
communication Interface Mode. (Note that RTS stands for Ready To Send
and ADDC stands for Automatic Data Direction Control.)

Keep the following points in mind when setting the DIP switches.

RS-232 Console

To use the serial port as a console connection, such as when using MOXA
PComm Terminal Emu lator or HyperTerminal, set SW1 to the ON position.

Telnet Connection

Some setup procedures can be carried out through a Telnet connection,
during which data is transmitted through NPort Express’s Ethernet port.

However, you must set SW1 to the OFF position to establish a Telnet
connection.

NPort Express DE-211 Serial Installation

23

Enabling a Termination Resistor

For RS-422/485 serial communications, when an electrical signal travels
through two different resistance junctions in a transmission line, the
impedance mismatch will sometimes cause signal reflection. Signal
reflection causes signal distortion, which in turn will contribute to
communication errors. The solution to this problem is to establish the
same impedance at the line ends as in the line itself, by terminating them
with resistors.

The impedance of the termination resistor should equal the characteristic
impedance of the transmission line. The resistors should be added near
the receiving side.

Enabling the Built-In 120 Ω Terminator

To enable NPort Express’s built-in 120 Ω termination resistor, you must
short the bottom two pins of jumper 6 (JP6), on DE-211’s circuit board. To
do this:

1. Use a screwdriver to remove DE-211’s outer protective case, and

then locate JP6, as shown in the figures below.

2. By default, the top two pins of JP6 are shorted, which means that the

built-in 120 Ω termination resistor is disabled (completely removing
the jumper from the pins also disables the resistor).

3. Use the jumper to short the bottom two pins of JP6 to enable the

built-in 120 Ω termination resistor.

24

Enabling a User-Supplied Terminator

When using the terminal block, you may install your own external
terminator resistor by connecting the ends of the resistor directly to
inputs 2 and 3, or by connecting the two ends of the resistor to the wires
that emanate from inputs 2 and 3, as shown in the following diagrams.

Connecting to the Ethernet Port

Connecting to a Hub or Switch

For most applications, you will simply plug one end of your Ethernet cable
into NPort Express’s 10BaseT port, and the other end into a Hub or Switch
that is connected to your network. In this case, you should use a standard
straight-through Ethernet cable, which is readily available from many
commercial vendors. If necessary however, you can make your own cable
by referring to the follo wing cable wiring diagra m.

Connecting to a PC

In some cases, such as when configuring drivers and software, you will
find it convenient to hook NPort Express directly to your computer’s
Ethernet card. To do this, you will need to use a cross-over Ethernet cable.
This type of Ethernet cable is harder to find, although you can make your
own cable by referring to the following cable wiring diagram.

Using the Power Adapter

Take the following steps to connect NPort Express’s power adapter.

1. Plug the power adapter’s DC plug into NPort Express’s DC-IN jack.

2. Plug the power adapter into an electrical outlet.

Note that there is no on/off switch. The server turns on as soon as the
connected power adapter is plugged into a live outlet. The red PWR light
on NPort Express’s top panel will glow to indicate that it is receiving
power.
